double scrollbars on resizing with maximize and restore browser-window - c#

I have the following situation:
I've got a header, content, and a footer.
Now the header and footer have a fixed height and are always on the screen.
css for footer and header:
#footer {
background-color:#e6e6e6;
width:100%;
height:46px;
bottom:0;
left:0;
position:fixed;
border-top:1px solid #7F8C8D;
z-index:101;
}
#header {
border-bottom:1px solid black;
height:45px;
background-color:#828282;
color:#FFF;
position:absolute;
top:0;
left:0;
right:0;
z-index:105;
width:100%;
box-sizing:border-box;
}
As for the content i have the following:
#content {
background: #9cbbe3 url(../img/backgr.gif) repeat-x;
right:0;
left:0;
background-size:auto;
position: absolute; top: 0px; bottom: 0px;
overflow: auto;
}
Now this works! at first...
But then i go and maximize and minimize the window, and i end up with two scroll-bars.
When i refresh the page the problem is fixed. and re-sizing works as far as I've noticed. but when maximizing and restoring the window i end up with two scroll-bars.
How can i solve this preferably using CSS?

Maybe this works out for you:
html, body { overflow: hidden; }

Try changing your overflow
overflow: auto;
to:
overflow: hidden;

How do I display a YouTube video in webViewer?

I'm trying to play a video in my C# WinForm.
Here is what I have so far:
I have a webViewer control in my form, and the following code:
// Play YouTube video in webBrowser1
string url = "https://www.youtube.com/watch?v=5aCbWqKl-wU";
string html = "<html><head>";
html += "<meta content='IE=Edge' http-equiv='X-UA-Compatible'/>";
html += "<iframe id='video' src='https://www.youtube.com/embed/{0}' style=\"padding: 0px; width: 100%; height: 100%; border: none; display: block;\" allowfullscreen></iframe>";
html += "</body></html>";
webBrowser1.DocumentText = string.Format(html, url.Split('=')[1]);
Here is what it looks like when I run my app:
The problem is that the video does not fill up the entire webViewer (which is the white part in the image).
I have the webViewer1.Anchor property set to all, so when I resize the form, the webViewer resizes based on the form.
Note:
When the user clicks the fullscreen button the problem is fixed. But this is a bad solution for me because it's a bad experience for the user. Plus, the user may not know that they need to click the fullscreen button. This is what that looks like:
How do I make the video take up the entire webViewer without the user having to click the fullscreen button?
Also, as a side-question, when the user clicks the "YouTube" button, it opens Internet Explorer, and not the default browser. How do I fix this?
You need to fix the styling of your page:
// Play YouTube video in webBrowser1
string url = "https://www.youtube.com/watch?v=5aCbWqKl-wU";
string html = "<html style='width: 100%; height: 100%; margin: 0; padding: 0;'><head>";
html += "<meta content='IE=Edge' http-equiv='X-UA-Compatible'/>";
html += "</head><body style='width: 100%; height: 100%; margin: 0; padding: 0;'>";
html += "<iframe id='video' src='https://www.youtube.com/embed/{0}' style=\"padding: 0px; width: 100%; height: 100%; border: none; display: block;\" allowfullscreen></iframe>";
html += "</body></html>";
webBrowser1.DocumentText = string.Format(html, url.Split('=')[1]);
This ensures that the HTML and BODY tags occupy 100% of the page, and that allows the child iframe to occupy 100% of the page. That generates this HTML:
<html style='width: 100%; height: 100%; margin: 0; padding: 0;'>
<head>
<meta content='IE=Edge' http-equiv='X-UA-Compatible'/>
</head>
<body style='width: 100%; height: 100%; margin: 0; padding: 0;'>
<iframe id='video' src='https://www.youtube.com/embed/5aCbWqKl-wU' style="padding: 0px; width: 100%; height: 100%; border: none; display: block;" allowfullscreen></iframe>
</body>
</html>
I think you need to set up an Aspect Ratio.

I am using vs2019. I don’t know why. After trying it, it is in a black state and does not display the video.

ASP.NET Background-clip: text; Not working

I'm new to .net core and wanted to know if im doing anything wrong or missing anything to get my Background-clip: text; to work, like it does in any other platforms...
I've also tried to debug this problem in multiple web browsers, such as Chrome and Microsoft Egde.
I've tried Background-clip: text; and -Webkit-Background-clip: text; and nothing seems to work. It says that the text value is not valid for Background-clip
Here's my code: Style.css
.text-container p {
-webkit-text-fill-color: transparent;
font-size: 150px;
background-image: url("https://s31.postimg.cc/yaze1agjv/abstract-background-canvas-249798.jpg");
background-repeat: repeat-x;
background-position: bottom;
background-size: cover;
animation: animate 30s linear infinite;
text-align: center;
margin-top: 17%;
text-transform: uppercase;
font-weight: 900;
width: 100%;
height: 100%;
-webkit-background-clip: text;
background-clip: text;
}
#keyframes animate {
0% {
background-position: left 0px top 10px;
}
40% {
background-position: left 800px top 10px;
}
}
Index.cshtml
<html class="backimg">
<body>
<p class=text-container> Hello World!</p>
</body>
</html>
*** Edit: I tried to debug this problem on another text editor, and this code works fine. Is there something wrong with .NET core when it comes to background-clip: text; ? Online code editor : JSFiddle ( https://jsfiddle.net/2m6pwvqo/14/ )
you are right css syntax for media query, but it's not like that in Razor web page...
you can put extra # sign and try with below
##keyframes animate{
}

How to auto adjust WebBrowser control height in Windows Phone 7?

I have created a WebBrowser control in the xaml,
and bind some html via string to it. It's working fine .
But the WebBrowser will never auto adjust its height.
<phone:WebBrowser
HorizontalAlignment="Stretch"
Margin="0,6,0,0" Name="myWebView"
VerticalAlignment="Top" />
private void WebBrowser_OnLoaded(object sender, RoutedEventArgs e)
{
String htmlTags = "<html><head><meta charset='UTF-8'/><meta name=\"viewport\" content=\"width='480', initial-scale='1'\"></head><body><center>{0}</center></body></html>";
myWebView.NavigateToString(String.Format(htmlTags, getHTMLContent());
}
public string getHTMLContent()
{
StringBuilder htmlBody = new StringBuilder();
htmlBody.Append("<table cellpadding=\"0\" cellspacing=\"0\" width=\"704\" height=\"484\" background=\"https://known.com/img/back/123456.jpg\" style=\"background-repeat: no-repeat; background-position: center;\">");
htmlBody.Append("<tr>");
htmlBody.Append("<td valign=top>");
htmlBody.Append("<div style=\"position: absolute;\">");
htmlBody.Append("<div style=\"position: absolute; display: table; width: 132px; height: 132px; top: 44px; left: 44px; z-index:0;\">");
htmlBody.Append("<img src=\"https://known.com/img/icon/87654.jpg\" width=\"100%\" height=\"100%\"/>");
htmlBody.Append("</div>");
htmlBody.Append("<div style=\"position: absolute; display: table; width: 704px; height: 484px; top: 0px; left: 0px; z-index:0; \">");
htmlBody.Append("<img src=\"https://known.com/img/icon/234255.jpg\" width=\"100%\" height=\"100%\"/>");
htmlBody.Append("</div>");
htmlBody.Append("<div style=\"position: absolute; display: table; width: 440px; height: 264px; top: 184px; left: 184px; z-index:0; font-family:times; font-size:14px; color:#FFFFFF; \" align=\"center\">");
htmlBody.Append("<div style=\"display: table-cell;vertical-align: middle;\">");
htmlBody.Append("</div>");
htmlBody.Append("</div>");
htmlBody.Append("</div>");
htmlBody.Append("</td>");
htmlBody.Append("</tr>");
htmlBody.Append("</table>");
return htmlBody.ToString();
}
What I want the WebBrowser to be
1) Auto adjust its height depends on the HTML String. If i pass only one image mean, it should auto adjust depends on the image.
It there is no content mean, browser should hide itself.
2) Should not scrollable, because the WebBrowser already stretch its height to fit the content.
How can I make it? Please let me any idea to resolve my problem.
You need to use javascript to get the height of the rendered html and set it to your WebBrowser control.
Here is an implementation of this.

Maintain the SelectedNodeStyle of treeview while navigating Treeview on masterpage

Hi all i applied selectednodestyle for a treeview which works fine when i am not navigating. But on navigating i am unable to see the applied color for the treeview selected node. Here is my design in master page
<asp:TreeView ID="TreeViewCategories" runat="server" ExpandDepth="0" Style="min-height: 200px;
max-height: 500px;" NodeIndent="0" LeafNodeStyle-CssClass="LeafNodesStyle" CssClass="TreeView"
NodeStyle-CssClass="NodeStyle" ParentNodeStyle-CssClass="ParentNodeStyle" RootNodeStyle-CssClass="RootNodeStyle"
SelectedNodeStyle-CssClass="SelectedNodeStyle" LeafNodeStyle-Width="100%" NodeStyle-Width="100%"
ParentNodeStyle-Width="100%" RootNodeStyle-Width="100%" Font-Size="12pt">
<Nodes>
<asp:TreeNode Text="All Items" NavigateUrl="~/Default3.aspx" SelectAction="SelectExpand"
Value="All Items">
<asp:TreeNode Text="Hello" Value="Hello"></asp:TreeNode>
</asp:TreeNode>
</Nodes>
</asp:TreeView>
This is my css
<style type="text/css">
.TreeView
{
border-bottom: 1px dotted #B2B2B2 !important;
}
.TreeView div
{
margin-left: 5px;
}
.TreeView table
{
border-top: 1px dotted #B2B2B2 !important;
}
.TreeView div table
{
border-bottom: none !important;
border-top: none !important;
}
.TreeView table td
{
padding: 2px 0;
}
.LeafNodesStyle
{
}
.RootNodeStyle
{
}
/* ALL ELEMENTS */.NodeStyle
{
}
.ParentNodeStyle
{
/*background:yellow;*/
}
.SelectedNodeStyle
{
font-weight: bold;
color: #6799D1;
display: block;
padding: 2px 0 2px 3px;
}
</style>
But i am unable to apply the color for selected node after navigating to a page can any one help me
your codes are working Ok so is the CSS. if you will notice the text of the one youve selected became bold.
If your basis is in change of color of the text, there is some problem. If you would look at the source code, not only SelectedNodeStyle css style is applied on the item, but these also
NodeStyle FooterContent_TreeViewCategories_2 LeafNodesStyle FooterContent_TreeViewCategories_8 SelectedNodeStyle FooterContent_TreeViewCategories_10
so I suggest putting some !important on your css color for the change in color to take effect.
.SelectedNodeStyle
{
font-weight: bold;
color: #6799D1 !important;
display: block;
padding: 2px 0 2px 3px;
}

HTML/CSS Positioning Issue with asp:Label and span

When I do the following:
<asp:Label CssClass="someField" runat="server">*</asp:Label>
<asp:Label ID="someID" runat="server" Text="SomeText" AssociatedControlID="someACID"></asp:Label>
Or:
<span class="someField">*</span>
<asp:Label ID="someID" runat="server" Text="SomeText" AssociatedControlID="someACID"></asp:Label>
Css someField:
span.someField {
color: #CC0000;
font-weight: 600;
}
Css for label:
form label {
clear: left;
cursor: pointer;
display: block;
float: left;
font-size: 1em;
margin: 0 3px 4px 0;
padding: 4px 0 4px 5px;
width: 200px;
}
the output I get is
SomeText*
When what I want is
*SomeText
Anyone know why this is happening?
By setting float:left on the label you are taking it out of the flow of the document and causing it to render before the span. You need to either set the span to be a block layout and float it left as well or remove the float from the label.
UPDATE:
There's a good description of what floating does to elements and some considerations here: http://coding.smashingmagazine.com/2007/05/01/css-float-theory-things-you-should-know/
Another option
form label:after {
content: "*";
}
